Abstract

L'invention concerne un système de propulsion (120) pour un aéronef comportant un système d'air (206), ledit système de propulsion (120) comportant : - un carénage (112) présentant une grille ajourée (114), - un turboréacteur double flux (110) avec un étage de compression (202) et une veine secondaire (204), et - un système de prélèvement d'air (200) comportant un échangeur thermique (208), une canalisation chaude (250) connectée entre l'étage de compression (202) et le système d'air (206), et traversant l'échangeur thermique (208), et une canalisation froide (252) connectée entre la veine secondaire (204) et la grille ajourée (114), et traversant l'échangeur thermique (208). Le système de prélèvement d'air (200) comporte un volet (210) qui est arrangé au niveau de la grille ajourée (114) et qui est déplacé par un moteur (212) entre une position ouverte dans laquelle le volet (210) n'obture pas les trous de la grille ajourée (114) et une position fermée dans laquelle le volet (210) obture les trous de la grille ajourée (114). L'intégration de la fonction d'évacuation et de régulation au niveau de la grille ajourée (114) permet un gain de place, ce qui facilite l'intégration du système de prélèvement d'air (200) dans le système de propulsion (120).The invention relates to a propulsion system (120) for an aircraft comprising an air system (206), said propulsion system (120) comprising: - a fairing (112) having a perforated grid (114), - a turbojet double flow (110) with a compression stage (202) and a secondary stream (204), and - an air bleed system (200) comprising a heat exchanger (208), a hot pipe (250) connected between the 'compression stage (202) and the air system (206), and passing through the heat exchanger (208), and a cold pipe (252) connected between the secondary stream (204) and the perforated grid (114), and passing through the heat exchanger (208). The air sampling system (200) comprises a shutter (210) which is arranged at the level of the perforated grid (114) and which is moved by a motor (212) between an open position in which the shutter (210) n 'not closes the holes of the perforated grid (114) and a closed position in which the shutter (210) closes the holes of the perforated grid (114). The integration of the evacuation and regulation function at the level of the perforated grid (114) saves space, which facilitates the integration of the air sampling system (200) in the propulsion system (120 ).
